my pre-3e d&d gaming that took place on and off between 10-13, and 17-19 are mostly hazy memories. i know i mainly DMed when we first found the game.
When I played, it was mostly under a DM who didnt kill characters, but I remember one time I had a Paladin who was 7th or 9th level or somesuch, the highest we ever actually got, and he was criticalled by some sort of giant and died.
I was a little surprised, because I had never actually seen a character death as a player, but after checking the math I started to roll up a new character.
Pretty much the same experience when I started DMing 3e and killed a PC. Everyone was a little shocked that it actually happened, because all of their prior DMs never did it, but we quickly moved on.
